Abstract

La présente invention est un cathéter à commandes à distance destiné en principe à la chirurgie cardio-vasculaire, caractérisé par le fait qu'il permet à son utilisateur de commander directement, en partant de la poignée de l'instrument, l'orientation de sa tête et ceci au moyen d'un fil de commande (31) attaché à l'extrémité même de la tête du cathéter tout en étant décentré par rapport à l'axe de cette dernière d'une part, et à l'extrémité de l'arbre de traction (34) placé à l'intérieur de la poignée d'autre part, ce dernier pouvant se déplacer dans la direction de son axe et par conséquent tirer ou relacher le fil de commande (31) lorsque l'utilisateur imprime un mouvement de rotation à la bague de commande (37) entraínant par sa denture intérieure le pignon intermédiaire (36) ce dernier engrènant à son tour dans la denture (35) de l'arbre de traction (34) qui possède également un filetage vis (38) travaillant avec un filetage écrou fixe (39) par rapport à la poignée. The present invention is a control catheter with distance intended in principle for cardiovascular surgery, characterized by the fact that it allows its user to order directly from the handle the instrument, the orientation of its head and this by means of a wire control (31) attached to the very end of the head of the catheter while being off-center with respect to the axis of this last on the one hand, and at the end of the traction shaft (34) placed inside the handle on the other hand, the latter being able to move in the direction of its axis and by therefore pull or release the control wire (31) when the user prints a rotational movement on the ring control (37) driving by its internal toothing the intermediate pinion (36) the latter in turn meshing in the toothing (35) of the traction shaft (34) which has also a screw thread (38) working with a thread fixed nut (39) relative to the handle.

La tête de ce cathéter comporte un ressort boudin cylindrique (28) coiffé d'une pièce de révolution à tête arrondie (29) appelée communément bouterolle, ces deux éléments au moins étant surmoulés d'un matériau (32) du genre caoutchouc de manière à réaliser une chambre étanche (33), est une construction qui permet d'obtenir par l'injection dans cette chambre (33) d'un fluide sous pression lui-même conjugué à la traction exercée sur le fil de commande (31), le raidissement de cette tête dans la forme recherchée tout en évitant son gonflement grâce aux spires du ressort boudin (28) pour les forces latérales du fluide et d'un fil (30) en U renversé passant par la fante de la bouterolle (29) et fixé par ses deux extrémités à la base du ressort (28) pour ce qui concerne les forces longitudinales. En ce qui concerne le ballon classique gonflé habituellement par un gaz, ce ballon pourrait être remplacé par une sorte de vessie 19 gonflable par un liquide en l'occurence un liquide de contraste introduit par le tuyau (4) et faisant suite dans la gaine (16) au travers de la chambre (14) pour s'échapper par les orifices (42) et (43) pratiqués dans cette gaine. The head of this catheter has a coil spring cylindrical (28) capped with a piece of revolution with a head rounded (29) commonly called snap, these two elements at least being overmolded with a material (32) of the rubber like to make a room waterproof (33), is a construction which makes it possible to obtain by injecting into this chamber (33) a pressurized fluid itself combined with the traction exerted on the wire control (31), the stiffening of this head in the form sought while avoiding swelling thanks to the turns the coil spring (28) for the lateral forces of the fluid and an inverted U-shaped wire (30) passing through the edge of the snap (29) and fixed by its two ends to the base of the spring (28) with regard to the longitudinal forces. Regarding the classic balloon usually inflated by a gas, this balloon could be replaced by a kind of bladder 19 inflatable by a liquid in this case a liquid contrast introduced by the pipe (4) and following in the sheath (16) through the chamber (14) to escape by the orifices (42) and (43) formed in this sheath.

Pour ce qui est de la fonction bien connue d'introduire du liquide de contraste à l'extérieure de la tête de l'instrument et à l'intérieur du vaisseau, ce lqiuide sera injecté dans le tuyau 2 pour s'échapper ensuite par les deux orifices (24) et (25) du bâti (17) du présent cathéter. In terms of the well-known function of introducing contrast liquid on the outside of the instrument head and inside the vessel, this fluid will be injected into the pipe 2 to then escape through the two openings (24) and (25) of the frame (17) of the present catheter.
